Application filed. Apri 1 3,

This invention relates to anchoring devices for hand rails and the likeadapted to be inserted in concrete or other similar base, and the objectis toprovide a simple and inexpensive device of tlre characterstatedwhich consists of a hollow base member adapted to be anchored in theconcrete and having, an adjustable member threaded for the reception ofthe-rail end and adjustable with the aXis of the threaded apertures atvarious angular positions thereby truing the same relative to the axisof the hand rail or structure to be inserted therein. I

A further object, is to provide a device that may be secured to the moldboards utilized in forming a concrete or similar plastic structure tosupport the same in proper position while the plastic material is beingplaced. I n y Instructures of this character formed molding, the surfacethereof usually is not exactly at a right angle for instance to someother portion of the structure with which the hand rail or likestructures: is to be attached. Subsequent to the erection of concrete orplastic structure and removal of the mold boards, my 1Inproved anchoringdevice remains set in the hardened plastic material. The adjustablemember within the hollow base is loose and, by means of threaded studs,bolts or the like, this member may be brought to'position with the axisof the threaded aperture thereof at the proper angle to receive a handrail supported by a similar device on another portion of the structure.The object here is to secure this desirable result by means inexpensivein character and readily adjustable even by unskilled labor in themanner and for the purpose stated. These objects and the several novelfeatures of the invention are hereinafter more fully described andclaimed, and the preferred form of construction of an anchoring deviceembodying my invention s shown in the accompanying drawing in which-- vFig. 1 is an elevation of} a stair showing my improved anchoring deviceas applied thereto and part of a hand rail supported by the z-rnchoringdevice. I

vious' to erection of the structure in Which theanchor is" to be set-Ldeviceconsis'ts of a hollow base preferably formed of the ring likemember 1 whichis L shaped in cross" section as shown in 2. I Theintur'ned fl aiige' 20f thedevice provides a comparatively large centralopening in what is" hereafter termed the face of the device, and, thisflange hasthe edge form'edto provide a spherical seat for theretain'er f3 which has' the 'spherical outer surface 4' and a central threadedaperturej5 for the hand rail. Thisreta iner 3 has a flange or lug's 6provided with threaded apertures for'the bolts 7 of which there are fourarranged" in pairs in diametrically opposite relation. To the flange 8of the member 1 is secured a sheet metal plate S) havingseveralapertures 10 therein all within a. circle of the diameter of thethreaded aperture. To the flange 8 is also secured anchoring members 11of which there may be several and preferably attached by rivetingorwelding to the member 1 as shown extending outwardly at an angle. to thebase; These" members provide anchor strips set in the concrete asindicated in Fig. 2; The flanges of the member 1 has aseries ofapertures for' the bolts abov'ennenti'onedwhich are to be inserted afterthe structure has' b'een erectd. p

In ig. 31 have shown the device attached to amold' board by nails forinstance passing through the apertures 10 of the plate 9. At; thisti'me'the retaine'i'f3 has the outer facelpractically flush with theouter surface of the flange Q'permittingthe structure to be secured inthe manner shown in Fig. 3 to the mold board. These nails may be drivenonly lightly in the mold board which is usuof wood' and thus, after theconcrete is set and the anchoring device fixed in position, thenioldboard may be readily with drawn and the nails may be cut 01% or driveninto the concrete. The several bolts' 7 may then be inserted in'. theapertures provided therefor in the flange 2 and into the threadedapertures in the flange or lug 6 of the retainer 3' and, by turning thebolts, the retainer is drawn outwardly of the recess of the base to aposition similar tu that shown in Fig. 2 in which the spherical face ofthe retainers fits the" spherical seat proi' ided in the edge of theflange 2 and, as indicated in the said drawing, the axis ofthe threadedapertures may be at other than a right angle to the surface of theconcrete or surface of being practically flush with the surface of theflange 2 practically flush therewith. The bolt apertures in the flange 2are greater in diameter than the bolts 7 permitting the bolt to occupy aposition at an angle to the axis of the aperture.

It is to be noted that the bolts 7 are arranged in pairs indiametrically opposite position, as stated, which enables the retainerto be trued relative to the axis of the hand rail member to be securedtherein. This is accomplished by thread ing one or the other of thebolts to a greater extent than the diametrically opposite one of a pair,and the retainer may be trued in two directions for the purpose stated.By this arrangement the device is adapted for use in any position on ahorizontal or vertical face of a structure or angular face thereof asmay be necessary and can be trued to correct position to receive thehand rail supported at other points on the structure. Thus, if the base,inthe hardening of the plastic structure, takes a poslion not trulyflush with the surface there of or, being'fiush with the surface, thesaid surface is not at the proper angle relative to'other surfaces ofthe structure to which the rail is to be attached the retainer, by asimple manipulation of the bolts, may be adjusted to correct positionfor the purpose stated;

Having thus briefly described my invention, what I claim and desire tosecure by Letters Patent of the United States is- 1. An anchoring devicefor the purpose stated comprising a base adapted to be embedded inconcrete, said base being of hollow. form and having an apertured facepractically flush with the concrete surface,
